sceptrum

Borrowed from Ancient Greek σκῆπτρον (skêptron), derived from σκήπτω (skḗptō, “to press one thing against another”) +‎ -τρον (-tron, instrument noun suffix).

• (Classical) IPA^(key): /ˈskeːp.trum/, [ˈs̠keːpt̪rʊ̃ˑ]
• (modern Italianate Ecclesiastical) IPA^(key): /ˈʃep.trum/, [ˈʃɛpt̪rum]

scēptrum n (genitive scēptrī); second declension

1. sceptre (royal staff, symbol of authority)
   • 29 BCE – 19 BCE, Virgil, Aeneid 1.56–57:

     [...] celsā sedet Aeolus arce
     scēptra tenēns, mollitque animōs et temperat īrās.

     [King] Aeolus sits in his high citadel, holding his scepter, and [he is] soothing the passions [of the winds] and tempering their angry spirits.
     (Figuratively, by holding his scepter the king is wielding his authority. Note the poetic plural [sceptra] used in place of the singular [sceptrum]. See Aeolus (son of Hippotes).)

Second-declension noun (neuter).
